Cloudbase Solutions
• Company started in Italy as .Net / Linux
interop dev and consulting
• Branch started in Timisoara in 2012 to hire
devs and provide colocation services
• Started using OpenStack for the internal
IDC
• Added Hyper-V support
• OpenStack business exploded 
Agenda
•
•
•
•
•
•
•
•
OpenStack + Hyper-V integration
FreeRDP HTML5 dashboard
OpenVSwitch on Windows
Cloudbase-Init
Windows Server 2012 Eval Image
Crowbar integration
Cross Cloud Migration
Havana plans
Hyper-V 2012 availability
• FREE edition
– Full Hypervisor
– Minimum OS support
• Minimum impact on security updates, etc
• Windows Server 2012
– Just enable the related role
• Windows 8
– For workstation / testing / development usage
Hyper-V / Windows
Openstack components

RDP console (instead of VNC)
• Deprecated Nova network is not supported beyond “flat”
networking
– All Hyper-V networking features are part of Quantum
Quantum
• Hyper-V plugin is part of Quantum since
Jan 2013
• Supported network types:
–
–
–
–
VLAN
Flat
Local
NVGRE (Havana)
• Plugin / agent model
– Plugin runs in quantum-server (controller)
– Agent runs on each Hyper-V compute node
Quantum OVS interop
• Quantum plugin / agent AMQP RPC protocol is
compatible with OpenVSwitch!!
• You can use the OVS plugin with Hyper-V
agents (or vice versa)
– Limited to compatible L2 protocols: Flat / VLAN
• You can use the L3 and DHCP agents with
the Hyper-V plugin
– Using the OVS L2 agent on the networking nodes
• Great for interoperability (e.g. KVM + Hyper-V)
Hyper-V OpenVSwitch!
We officially started porting
OpenVSwitch to Windows!!
Why OpenVSwitch?
• De facto standard for SDN
• Great interoperability
– Hyper-V / KVM / etc
• OpenFlow
• Tunnelling
– VXLAN
– GRE
• Quantum OVS plugin
– No need for a different one
OpenVSwitch porting
•
•
•
•
Porting Posix calls to Windows API
Same CLI as on Linux
Open Source
Windows kernel drivers
– NDIS Hyper-V extensions
• VXLAN, GRE
– Best performance
• Support for Hyper-V 2012 and above
OpenVSwitch
Windows Kernel drivers
Typical Quantum setup
VLAN drivers issues
• BEWARE: Some Windows NIC drivers disable
VLAN access by default!
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentCont
rolSet\Control\Class\{4d36e972-e325-11ce-bfc108002be10318}
• Look in all the child keys xxxx, e.g. 0001, 0002 etc
for a value "VLanFiltering". Make sure that if
present it's set to 0.
• In case of changes, reboot the server or restart the
corresponding adapters.
FreeRDP
• FreeRDP is an amazing RDP open source
client.
– Apache 2 license
– Multiplatform
• Linux
• Mac OS X
• Windows
• It provides support for the PCB parameter
required by Hyper-V
• We are using it as a standalone client on the
free Hyper-V server and on Linux, Mac OS X
FreeRDP-WebConnect
• An HTML5 RDP client based on canvas and
websockets
– Similar to NoVNC
• Uses a C++ demon (wsgate) to handle
websocket connections and connect to the
RDP server
– Better performance compared to the Python
proxy used by NoVNC
• We provided support for Hyper-V
Nova Compute Installer
• Independent Python environment to avoid
conflicts with existing applications
• Installs and registers all the required
dependencies
• Generates dynamically a nova.conf file based
on the parameters provided by the user
Nova Compute Installer
• Creates a new Hyper-V external switch if
required
• Registers nova-compute as a service and
starts it
• Registers quantum-hyperv-agent as a service
and starts it (optional)
• Enables the Microsoft iSCSI Initiator service
(optional)
Unattended mode
•
Can be installed in fully unattended mode, great for:
– Chef, Puppet, Group Policies…

Windows Cloud-Init
• Cloudbase-init (aka Windows Cloud-Init)
– Similar to the Linux cloud-init
– License: Apache 2
• Porting Cloud-Init to Linux was not possible
– It requires some major refactoring
• Supported data sources:
– OpenStack HTTP metadata
– ConfigDrive V2
– EC2 HTTP metadata (contributed by Mirantis)
Windows Cloud-Init
• Plugin based architecture
• Supported plugins:
–
–
–

key
3. Password is POSTed to the metadata service
4. Password can be retrieved by the client and
decrypted with the SSH private key
–
nova get-password vm1 .ssh/id_rsa
Windows Installer
Unattended mode
• Like all our installers, it can be executed in
fully unattended mode:
• msiexec /i CloudbaseInitSetup.msi /qn
/l*v log.txt

Crowbar
•
•
•
•
Big part of Dell’s cloud strategy
Bare-metal deployment
vendor independent

configuration
• Provisioning via Crowbar web site
• Barclams
– Configuration
– Chef recipes
Crowbar + HyperV
Cross Cloud migration
• Vendor lock-in anybody? 
• Just a few clicks to migrate virtual
workloads to and from:
– Amazon AWS
– Azure
– OpenStack
• Including RackSpace
– VMWare vSphere
– MS System Center
• Currently in beta
Havana!!
• Planning for Havana now!
